Simple d1-d9 transition metal complexes
- Colour arises from d-d transitions
- Excited states very short lived
- Decay by internal conversion, a sequence of complicated steps that convert electronic energy into thermal energy

Magnetite
- Magnetite, Fe3O4 is a mixed valence iron oxide, containing both Fe2+ and Fe3+
- Its electrical conductivity is a million times greater than isovalent Fe2O3, which contains only Fe3+
Prussian blue
- Prussian blue, , also contains both Fe2+ and Fe3+
- A three-dimensional coordination network of octahedral low-spin {FeII(CN)6} and high-spin {FeIII(NC)6} nodes
- Its intense blue colour is due to electron transfer from Fe2+ to Fe3+
